If your dog can’t get enough peanut butter, these Vegan Peanut Butter & Oat Cookies will quickly become their favorite treat. They combine the rich, nutty flavor that dogs love with ingredients that are gentle on digestion and packed with fiber. The best part is you only need a few simple ingredients to make a batch that’s both healthy and irresistible to your furry friend.
Ingredients: Only the Best for Your Pup

The ingredients for these treats are simple but carefully chosen to support your dog’s health:
- 1 cup rolled oats – High in fiber and easy on sensitive stomachs.
- 1/2 cup natural peanut butter – Packed with protein and healthy fats. Make sure it’s xylitol-free.
- 1/2 banana, mashed – Adds natural sweetness, potassium, and helps bind the dough.
Step-by-Step Instructions: Making These Peanut Butter & Oat Cookies
Preheat the Oven
Set the oven to 350°F (175°C) and line a baking sheet with parchment paper or lightly spray with oil.
Mash the Banana
Mash the banana in a small bowl until smooth to create a paste-like consistency.
Combine Ingredients
Mix the oats, mashed banana, and peanut butter in a large bowl. Stir until it forms a thick, sticky dough. Add a splash of water if needed.
Shape the Cookies
- Scoop small portions of dough.
- Roll them into balls and flatten slightly on the baking sheet.
- Leave some space between each cookie.
Bake
Bake for 15-20 minutes or until golden brown and firm. For a crunchier texture, leave them in the turned-off oven for a few extra minutes.
Cool & Serve
Allow cookies to cool completely before serving your dog.
Can It Be Done in the Air Fryer?
Yes! Follow these steps:
- Preheat air fryer to 320°F (160°C).
- Place cookies in a single layer (no stacking).
- Bake for 10-12 minutes, keeping an eye to avoid over-crisping.
Air fryer cookies are slightly crunchier but equally delicious.
Why These Ingredients Are Great for Dogs

- Oats – Gentle fiber, vitamins, and minerals for digestive health.
